You may have heard that nothing escapes the gravitational grasp of a black hole, not even light. This is true in the immediate vicinity of a black hole, but a bit farther out-in disks of material that swirl around some black holes-light can escape. In fact, this is the reason actively growing black holes shine with brilliant X-rays.

Engineers at Caltech have shown that atoms in optical cavities-tiny boxes for light-could be foundational to the creation of a quantum internet. Quantum networks would connect quantum computers through a system that also operates at a quantum, rather than classical, level.

As of March 20, more than 8,700 people worldwide had died of COVID-19, the disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Caltech trustee David Ho (BS '74) of the Aaron Diamond AIDS Research Center, Columbia University, says that this is just the tip of the iceberg.

The microscopic populations of bacteria in our intestines are, in some ways, just like us: They live in communities, eat, work, reproduce, and eventually die. Many of these bacterial species live in harmony with our bodies, providing benefits to us in exchange for nutrients and shelter.

To Joseph Falson , who recently joined Caltech as assistant professor of materials science, electrons are like exotic supercars because they possess amazing capabilities. Consider the phenomenon of superconductivity, in which paired electrons fly unimpeded, resulting in materials that display zero electrical resistance.

Severe flooding throughout the Midwest-which triggered a delayed growing season for crops in the region-led to a reduction of 100 million metric tons of net carbon uptake during June and July of 2019, according to a new study.

Humans have a number of ways to learn how to do new things. One of those ways is through observation: watching another person perform a task, and then doing what they did. Think of a child that learns how to "adult" by observing their parents as they pay for groceries or make a phone call.
